| Practice | Relative effectiveness | Method | Image1 |
|---|---|---|---|
| Temporary Construction Sediment Control | High | Implement and encourage practices to retain sediment within construction project area; see Temporary Construction Erosion and Sediment Control Factsheets for additional information |  |
| Wind Erosion Control | High | Institute a local program for wetting of open construction surfaces and other sources for windblown pollutants. |  |
| Material Storage Control | High | Reduce or eliminate spill and leakage loss by properly inspecting, containing, and storing hazardous materials and having a cleanup plan that can be quickly and efficiently implemented. |  |
| Better Parking Lot Cleaning | High | Maintain streets and parking lots frequently and especially in the spring by sweeping, picking up litter, and repairing deterioration; pressure wash pavement only as needed and avoid using cleaning agents. |  |
| Proper Vehicle Management | High | Ensure that vehicles are fueled, maintained, washed and stored in a manner that prevents the release of harmful fluids, including oil, antifreeze, gasoline, battery acid, hydraulic and transmission fluids, and cleaning solutions. |  |
| Storm Sewer System Maintenance | High | Regularly clean debris from storm sewer inlets, remove sediment from catch basin sumps, and remove any illicit connections to storm sewer systems. |  |
| Better Impervious Surface Deicing | Moderate | Properly store and conservatively apply salt, sand, or other deicing substances in order to prevent excessive and/or unnecessary contamination; implement anti-icing and prewet salt techniques for increased deicing efficiency. |  |
| Better Turf Management | Moderate | Ensure that mowing, fertilization, pesticide application, and irrigation are completed in ways that will prevent or reduce grass clippings, sediment, and chemicals from entering storm sewer systems; use native vegetation where possible. |  |
